Title: Method for controlling tension of rolling material
Inventor: NAKADA TAKAMASA
IPC: B21B37/48
Filed: 1983-05-27
Abstract: PURPOSE:To prevent the occurrence of an accident by operating the total sum of a rolling load and a conversion value of a tension to a rolling load, as an equivalent external rolling force, and controlling an interstand tension in correspondence with a variation portion when the force varies with respect to a reference equivalent external rolling force. CONSTITUTION:When a rolling load varies by biting the skid-mark part of a rolling material S between work rolls 7, 7; an equivalent external rolling force varies to make its variation portion a finite value, and a shared portion of tension and a shared portion of rear tension are operated, and a rear tension commanding operator 50 gives a tension-control commanding value to a rear tension controller 60. As a result, a roll-speed controlling device 11 feedback-controls the rotating speed of a work-roll driving motor so as to eliminate the deviation between a new roll-speed commanding value and a speed feedback quantity. As a result, a tension-load conversion value of the material S decreases and a rolling load burdened on the material S increases as compared with a conventional method. Accordingly, a suddenly decreased rolling load is immediately recovered, and a drawing to rolls is prevented.
